Planar rod

The following table details the forks known to access most planes. "Material" is the substance out of which the fork was made, usually metal.
"Pitch" is the single note to which an individual fork was tuned. If a plane had layers, this note always led to the first layer of that plane. Quasi-elemental planes could be reached by using a fork tuned sharp for positive planes and flat for negative planes. "Chord", in the table, indicates that multiple forks were required to ring in harmony. Major chords usually took one to the second layer of a plane, while minor chords took one to the third layer. More complicated harmonies were rumored to be able to reach other layers.
